well after giving it some thought and reading all the PP threads and hunting the net for tales of T4 tuning i have come to the conclusion its time to tune....plus i have had a cheeky insurance payout also I:

so my plans are

Van is a 1998 2.5TDI ACV 102bhp

stainless decat exhaust (done)
EGR Blank (done)

now the next phase

Volvo K14 TDI Turbocharger (bought)

Bigger Nozzles (to get)

Custom remap (to sort)

IC Water Spray (Just for fun)

Ram Air Induction (not sure of value read somwhere that you only get about 0.5-1.0 psi at 100mph)

So thats my plan now im looking for an idea of what the above is likely to cost if i took it to a tuner a said there you go i want 200bhp!

any thoughts or coments greatfully received i will be running a thread on this project and hopefully doing some BHP Dyno runs before during and after to show what each mod does.....

hi mate am going down that road but not 200 bhp mine will be about 160 - 170 ish ihave already been told clutch trouble and will need bigger brakes if i drive it hard and of course on a private road got my intercooler in and got me 150 bhp nozzles just ordered the injector bodies and then in for the job so nearly there Rasp:will be good to see how you get on keep us posted mate :ILU: sorry for got to say it will cost me about £700 i have done the hard work myself and thats not doing the brakes or clucth yet i was going to try it and see how i get on first and go from there good luck buddy

its going to run out of steam way to quick down to gearing a 88bhp box would of been better .

i wouldnt persnoaly of chosen the k14 turbo would of gone for a holset or a k26 , failing them would of pushed the standard turbo with few modifactions to 200ish with still a good spool up without running to much so was just creating hot air .

a decent clutch is going to be needed as the standard one will not cope or come close .

not sure if the maf will need upgrading to acheive those powers either .

thanks darren well i reckon getting the turbo to fit ie getting an adapter plate etc and the remap will be the most costly on top of cost of parts...

of course any south west tuners that fancy having a dabble with my T4 to see if it opens up a new market for them in these difficult economic times are more than welcome to use my T4 as a prototypeI: LOLLOL:

As I understand it, the 102bhp box is the stronger of the two units.
The top ratio may be shorter (after you have modified the gearing) but if you are happy with the cruising speed and RPM now then why change it?
The 102 box has had over 350bhp and loads of torque through it with little or no problems (appart from on the drag strip)
I will be keeping my eye open for a 88bhp VW box as a spare for experimental reasons but will be stripping and beafing it up as needed (+ LSD if I can find one)

All good points....Im now starting to search around for a tuner who can do it....any ideas in the southwest....I guess Nozzles and turbo (adapter plate) can be done by any competent mechanic fabricator its just the custom remap...although the complete package would be good I have my eye on RK Engineering I have heard great things about them...........A:A:

155bhp PP has been proven tested and works.......my plan is to expand on the great work already done by others....thats what this forum and T4 ownership is all about ....individuality and and takening things to the next level....

Following what shadowmaker has said on various other threads/forums the 2.5 Tdi is capable of 200bhp + without to many reliability issues... if you could have a reliable 200bhp wouldnt you want it? after all you must have wanted more power to have gone down the PP route. Its all trial and error! as for deep pockets well will have to put some overtime in if needed...... and as for why?....why not?I:

Too many issues! That is simply too many in itself, at no time do I want to be breaking down due to my own 'tinkerings'.

Yes shadowmaker has done alot to his T4, he is one man and the video of his strip run was like a clip off James Bond with a crazy amount of smoke. I:

I will read with interest your project and hopefully you won't have to put in too much overtime to replace turbo's £££, gearboxes ££££ and the cheapest of all the clutch ££. I don't think it will be just a case of working a saturday morning on overtime to cover these prices. But good luck all the same. T:

Have had the above symptoms for a while on AJT t4 .After a little thought and research found the problem to be the so called pendulum mount ,which connects the outside end of the gearbox to the sub frame .It has a large rubber bush at the sub frame end which had disintegrated after twenty years...

Hi everyone
Advice needed please. I have a 1998 W reg t4 2.5 TDI. I had the engine replaced with a reconditioned one after the water pump failed and destroyed the original engine. The fuel pump and injectors form the old engine were fitted to the new reconditioned engine. This is where the...

A friend of mine GAVST4, Has just called me,
He changed from 4th to 3rd gear earlier, and large clunk sound from up front, now engine jumping backs and forwards, and vibrating heavily through the cab, Any idea on location of them on a 96 1.9td??
Thanks guys

Hi all
I have a t4 with a 2.0 ACC engine. I need an exhaust manifold but they are like hens teeth and the ones available are silly money.
I have heard that the manifold from a 1.9 diesel 1x engine (readily available and much cheaper) will fit onto the head but come out at a slightly different...

Well it all started like I imagine a lot of engine conversions start, the old engine died. We debated replacing or repairing the original AJT engine but in the end we chose something a little bit more modern.
